Here’s a funny fact: The best time to go is at 11am. Why? The first post-Christmas deliveries arrive. Fresh bread. Fresh pastries. The shelves look magical. It’s like Christmas Day, but less presents and more custard doughnuts.
Also, don’t expect the full deli counter. They might be running a “limited offer” service. The cheese guy might not be slicing your Red Leicester on a fancy machine. He’ll hand you a pre-packed wedge. It’s fine. It’s still M&S.
The Verdict for 2026
Here’s the punchline for your calendar: Boxing Day 2026 is a Friday. That matters. A Friday Boxing Day means people are off work. Saturday is the weekend. This creates a three-day ritual of lazy eating. M&S knows you’ll need to restock for the Saturday fried breakfast.
So, they will likely open, but later than usual. Think 10am or 11am. Not the crack of dawn. They close early, too. By 5pm, the staff are back with their families. Respect that.
